@LaurelHillCraze has posted about it several times, but the important takeaway is that it makes very wet, very sticky snow fast and relatively quietly
, with the additional feature of having extra-sharp crystals so it locks to itself. Think very solid snowballs and very good float on thin cover, like when it side-drifts into glades.
Also a bitch to wax for but once you know you know. Oh, and bring a Skigee, coz it sticks to goggles like crazy.
